Hi,
Just to comment: You don't need ICT. The usage of H.323 gw in CallManager is the recommended way when integrating with CME. ICT is used for communication between CallManager clusters.
Now, you can also check if there's a codec mismatch.
Hope it helps, please rate if it does.

Adrian.

to call cucm from cme, you need voip dial-peer with destination-pattern [cucm range] and session-target [cucm.ip.add]

What tone are you hearing when you call CUCM phones from CME? Can you attach a 'debug voip ccapi inout' from the gateway and run a test call. Make sure your inbound CSS on your trunk in CUCM is applied and has access to the phones in CUCM you're trying to dial.
HTH,

only to confirm this line:
session-target ipv4;10.115.10.16(cucm ip)
I don't have a router now to confirm if the cli will accept ;
So confirm you do it as ipv4:10.115.10.16
